Contactor and dangler assembly for plating barrel

A dangler assembly for an electro-chemical apparatus comprising in combination:

• an elongated electrical conductor, an insulating sheath closely surrounding said conductor, an electrical connector disposed at one terminal end of said conductor, and, a contactor disposed at the opposite terminal end of said conductor;
• said contactor comprising a generally cylindrical openended casing having opposed inner and outer ends with a first bore section extending axially thereinto from said outer end receiving a longitudinal portion of said electrical conductor and insulating sheath adjacent said conductor opposite terminal end, a second bore section communicating with said first bore section extending further axially into said casing toward said inner end, having a threaded side wall at least substantially over the length thereof, and receiving a portion of the length of said conductor at said conductor opposite end, and a thrid bore section communicating between said second bore section and said casing inner end axially of said casing;
• and an elongated threaded fastener extending from said casing inner end through said third bore section and through at least a portion of said second bore section, and axially penetrating said conductor from said opposite terminal end thereof for radially expanding said conductor into retained engagement with the side wall of said second bore section, the threads of said fastener being of the opposite hand from the threads of said second bore section side wall.

A dangler cable contactor for use in a plating barrel wherein the contactor is fixedly securable to one end of an associated electrical cable having an electrical conductor and an outer insulating sheath, said contactor comprising:

• a casing having opposed outer and inner ends with an internal passageway extending therebetween, said passageway including first, second and third bore sections from said outer toward said inner end with each successive bore section from said first bore section decreasing in diameter;
• a threaded fastener having an elongated threaded shank receivable in said passageway from said inner end for fixedly securing said casing on said one end of said electrical cable;
• said second bore section being dimensioned to closely receive a section of said electrical conductor and including threads substantially over the length thereof of the opposite hand from the threads of said fastener;
• and, said first bore section being dimensioned to closely receive a section of said electrical conductor and said insulating sheath of said electrical cable, whereby insertion of said fastener into said passageway from said casing inner end causes said fastener to axially penetrate said electrical conductor and effect radial expansion of same into retained engagement with at least said second bore section.

A dangler assembly for an electro-chemical apparatus comprising in combination:

• an electrical cable including an insulating sheath surrounding an electrical conductor, an electrical connector disposed at one terminal end of said cable, and a contactor disposed at the opposite terminal end of said cable;
• said contactor comprising a generally cylindrical open-ended casing having opposed inner and outer ends with an internal passageway extending therebetween, said passageway including first, second, and third bore sections from said outer toward said inner end with each successive bore section from said first bore section decreasing in diameter;
• elongated fastening means receivable in said passageway from said inner end for fixedly securing said casing on said opposite terminal end of said cable;
• a portion of said electrical conductor closely received in said second bore section in compressive engagement between a threaded side wall of said second bore section and said fastening means;
• and, a portion of said electrical cable closely received in said first bore section, whereby insertion of said fastening means into said passageway from said casing inner end causes said fastening means to axially penetrate said electrical cable and effect radial expansion of same into retained engagement with said casing.
